Preparation method of dibutoxymethane

The invention discloses a preparation method of dibutoxymethane and relates to a preparation method of methane. The method comprises the process as follows: dimethoxymethane and n-butanol in a certain proportion are taken as raw materials, various liquid acids and supported liquid acids are taken as catalysts, the mixture is subjected to a reaction at the temperature of 0-160 DEG C and under the pressure of 0.1-10.0 MPa, and dibutoxymethane is generated in a high-selectivity manner; a heteropolyacid catalyst is prepared with an equivalent-volume impregnation method, and at least one of activated carbon, TiO2, Al2O3, SiO2, SBA-15 and MCM-41 is taken as a supporter; the supported heteropolyacid catalyst comprises heteropolyacid and a supporter for supporting the heteropolyacid, and heteropolyacid is one or more of phosphotungstic acid, silicotungstic acid, phosphomolybdic acid and silicomolybdic acid. A product prepared with the method is relatively single, the selectivity is high, required raw materials are cheap and easy to obtain, the whole process is simple to operate, no chemical substances polluting the environment are produced, and the preparation method belongs to an environment-friendly technological route.

Method for synthesizing butoxy methoxymethane

The invention provides a method for synthesizing methane, in particular to a method for synthesizing butoxy methoxymethane. A brand-new synthesis path for butyl cellosolve and the preparation method for butoxy methoxymethane are developed. The path is characterized in that butoxy methoxymethane is synthesized by methylal and butanol at high selectivity; butoxy methoxymethane is subjected to directional carbonylation, and butoxy methyl acetate is generated; butoxy methyl acetate is hydrogenated to generate butyl cellosolve and methyl alcohol. The preparation method includes the steps that dimethoxymethane and n-butyl alcohol at a certain ratio serve as raw materials, at certain temperature and pressure, molecular sieves of different topological structures serve as catalysts, and butoxy methoxymethane is prepared at high selectivity. The raw materials needed for the method are cheap and easy to get, the whole process is simple in operation, and the product is single, high in selectivity and suitable for industrial production, and has good application prospects.
